Just to point out that in this case we are pushing 26 psi of boost not 20 peak
Even with a rpm dependant duty cycle trim EBC the stock turbo will not hold 26 psi at red line
EBC's do help hold higher boost at a higher rpm if they have the rpm dependant duty cycle adjustment - (e.g. AVCR and the EBoost2)
However, it should be noted that forcing the turbo to hold higher boost at high rpms brings the turbo out of its efficency rating and starts to result in a lot of hot unstable hair dryer effect which leads to increased knock
In many cases it may be actually better to allow the boost to taper down slightly and smooth out the power band with the mivec and ign timing
